I must admit that I'm not very familiar with bananas and lenses.
Maybe I'm a bit more familiar with bananas than with lenses. I
personally prefer oranges and tomatoes anyway. Please check first
whether there is something useful in
http://www.ctan.org/tex-archive/info/symbols/comprehensive/symbols-a4.pdf
If there is no appropriate symbol available, you can probably define
it yourself, see

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
